Tailscale not opening windows interface to allow log in

i have installed Tailscale 1.28.0 on my home computer running windows 7 ultimate 64bit. After installation, the tailscale interface that allows one to sign in fails to start. This is the error am getting on checking the status of tailscale in CMD

Microsoft Windows [Version 6.1.7601]

C:\Users\DELMART>tailscale status
failed to connect to local tailscaled (which appears to be running as tailscaled
.exe, pid 1092). Got error: Failed to connect to local Tailscale daemon for /loc
alapi/v0/status; not running? Error: dial tcp connectex: No connection could be made because the target machine actively refused it.

I have disabled both the firewall and antivirus but still the problem persist.

Any help to get tailscale up and running will highly be appreciated.
